A rally car traveled for 2 hours 40 minutes at an average of speed pf 120km/h. The car consumes an average of 1 liter of fuel for every 4 kilometers. A liter of the fuel costs shillings 59. Calculate the amount of money spent on fuel.
Distance = 2 2/3h * 120km/h = 320km
¼ = x/59
59 = 4x
1 liter = 14.75
= 4720
liters used=320/4=80 liters
cost=59/liter*80 liters=80*59 schillngs
To calculate the amount of money spent on fuel, we need to know the total distance traveled.
Given that the rally car traveled for 2 hours 40 minutes at an average speed of 120 km/h, we need to convert the time into minutes.
2 hours = 2 * 60 minutes = 120 minutes
40 minutes = 40 minutes
Now, we can calculate the total time traveled:
Total time = 120 minutes + 40 minutes = 160 minutes
Next, we need to calculate the distance traveled. We know that the car's average speed is 120 km/h.
To calculate the distance traveled, we multiply the speed by the time:
Distance = Speed * Time
Distance = 120 km/h * 160 minutes
However, we need to convert the minutes back into hours:
160 minutes = 160/60 hours = 2 2/3 hours
Therefore, the distance traveled is:
Distance = 2 2/3 hours * 120 km/h = 320 km
Now that we have the distance traveled, we can calculate the amount of fuel consumed. We know that the car consumes an average of 1 liter of fuel for every 4 kilometers.
To calculate the amount of fuel consumed, we divide the distance by 4:
Fuel consumed = Distance / 4
Fuel consumed = 320 km / 4 = 80 liters
Finally, we calculate the amount of money spent on fuel. We know that 1 liter of fuel costs 59 shillings.
Amount spent on fuel = Fuel consumed * Fuel cost
Amount spent on fuel = 80 liters * 59 shillings
Calculating the result:
Amount spent on fuel = 4720 shillings
